BOLSTER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 568,925, dated October6, 1896.

Application filed August 21, 1896.

To all whom it ntay concern.-

Be it known that 1, CHARLES T. ScHoEN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania,haveinvented a certain new and useful Improvement inBolsters for Railway-Cars, of which the following is a full, clear, andexact description.

This invention relates more particularly to that class of bolsters forrailway-cars which are constructed of channel-beams, and especiallychannel-beams of pressed steel; and the object of the invention is toconstruct a bolster of channel-beams in which less riveting is requiredand fewer tie-plates are needed. and the strength ofwhich is equal to ifnot greater than bolsters constructed in accordance with previousinventions.

In carrying out my invention I form channet-beams and rivet themtogether by their webs, thus leaving their flanges standin g on twardly,all as I will proceed now more particularly to describe and finallyclaim.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a halftop plan and horizontal section of a truck-bolster. Fig. 2 is a sideelevation thereof. Fig. 3 is a central vertical cross-section, and Fig.4 an end view. Fig. 5 is ahalf top plan view and horizontal section ofthe bodybolster. Fig. 6 is aside elevation. Fig. '7 is a cross-sectiontaken in the plane of line 7 7. Fig. 8 is a central verticalcross-section taken in the plane of line 8 8, and Fig. 9 is an end View.

In constructing the truck-bolster I employ two similar channel-beams a,widest at their centers and tapering thence in converging lines towardtheir opposite ends, which ends are flat. The webs a a of these beamsare placed back to back and united by rivets b. The webs a a are spreadout centrally, as at (L in order to afford'a space for the passage ofthe king-bolt or center pin; and in order to reinforce the webscentrally I provide the bosses or bulges a extending longitudinallythereof. The flanges (t extend outwardly and away from one another andform continuous bearings at top and bottom for the reception of suchparts as are used in con- Serial No. 603,440. (No model.)

nection therewith, as, for example, the side bearings c c and the centerplate d. In order to reinforce the bolster at the point of greateststrain, the upper flanges may be provided with the bosses 6. Within thecavity formed by the curved portions a is arranged a center brace f,riveted to the Webs and having the central flanged orifice f for thereception of the king-bolt or center pin.

Chafing-plates or guides g for the bolstercolumns are constructed withtop and bottom flanges g, which are riveted to and between the top andbottom flanges of the beams at their ends, and these pieces g serve, inaddition to their described function, also as reinforces for said ends.

The body-bolster is similarly constructed of channel-beams h, which areriveted together by their webs with their flanges standing out wardlyaway from one another and having their lower sides diverging from theirends toward the center with their top ends or flanges on a level. Thewebs at their centers are bulged outwardly to form the socket 1 for thepassageof the king-bolt or center pin, and adjacent to this socket arearranged the braces 70, which are riveted to the webs and also to theflanges of the beams.

Z are the side bearings, and n is the center plate.

The spreading apart of the beams of the truck-bolster at their centers,with the longitudinal ribs pressed into the webs, effects additionalstrength for resisting transverse strains, such as are occasioned inbumpin The flanged pieces g, arranged on each side of the bolster ontheir opposite ends and set vertically therein and riveted to the topand bottomflanges, serve also to distribute the pressure from thebolster-springs, which set under each end of the bolster.

The flanged vertical central supports of the body-bolster, which, asbefore described, are riveted to the top and bottom flanges as well asto the webs of the beams, serve also to prevent the bending of theflanges of the beams at this point, due to torsional strains.

Bolsters constructed in accordance with the foregoing are equal instrength to those wherein the flanges are arranged adjacent to eachother, and, moreover, the cost of buildingis considerably less, inasmuchas the riveting is all done from the outside and is thereby more easilygot at. As already indicated, fewer rivets are required and fewertie-plates.

The channel-beams, both of the body and of the truck-bolsters, may bemade of steel plate pressed to shape, as also may be the side bearings,center plates, center brace, chafing-plate or guides, and the remainingmembers, excepting, of course, the rivets, and as to these any usualconstruction may be employed.

lVhat I claim is- 1. Abolster composed of channel-beams deeper at thecenter than at the ends and riveted together by their webs,substantially as described.

2. A bolster composed of channel-beams deeper at their centers than attheir ends and riveted together by their webs and having their centersspread apart, substantially as described.

3. A bolster composed of channel-beams riveted together by their websand having central longitudinal ribs, substantially as and for thepurpose described.

4. A bolster composed of channel-beams united by their webs and havingtheir ends provided with flanged pieces riveted thereto and constitutingcolumn-guides, substantially as described.

5. A'truck-bolster composed essentially of channel-beams rivetedtogether by their webs, spread apart at their centers, and supplied witha center brace having a king-pin' opening, substantially as described.

6. A bolster composed of channel-beams united back to back by theirwebs, and having their flanges constructed with bosses about midway ofthe length of the bolster, substantially as described.

. 7. A truck-bolster composed of channelbeams having their greatestvertical height at their center, and tapering thence convergently toopposite ends, spread apart at their center, and provided withlongitudinal reinforces in their webs, a king-bolt socket, andtie-plates at their ends, substantially as described.

8. A bod y-bolster composed of channelbeams having their greatest heightat their center and tapering thence toward their ends, united back toback by their webs, and having central vertical tie-plates,substantially as described.

9. A body-bolster composed of two channel-beams united back to back bytheir webs and having their webs spread apart to form a king-boltsocket, and central vertical tieplates or reinforces, substantially asdescribed.

In testimony whereof I have hereuntoset my hand this 18th day of August,A. D. 1896.
